| 摘 要： | 应用放射性同位素~(32)P与~(86)Rb对泡桐丛枝病病枝叶吸收磷钾规律进行了试验研究,同时对5种泡桐当年生正常实生苗进行了示踪试验,结果发现,抗病的种(如白花毛泡桐)吸收的磷少钾多,感病的种(如兰考桐)吸收的钾少磷多。

| Abstract: | A study by using isotope tracer 32P and 36Rb on shoots diseased by witche's broom of Paulownia was carried out. Simultaneously, experri-ments were also carried on normal 1 year old seedlings of 5 species of Paulownia. The results shows that the resistant species such as Paulow?nia tomentosa var. pallida absorb more K and less P, and the susceptible species such as Paulownia longata absorb more P and less K from soil. |
